new color spectrum before it is mixed with other image(s).
Note:
Color images (see below – the Color tab) are converted to
greyscale ones before mixing.
• The Invert check boxes inverts the corresponding source image
spectrum. It has the same effect as exchanging the left and right
colors selection.
• The Select 1+2 / 1+2+3 button selects between quads 1+2 or
quads 1+2+3 mixing modes.
• The Save button saves the actual setting as the custom preset.
The Color Tab
enables to colorize a gray scale image. An image already colored with
the use of the Mix 3 / Mix 4 tab cannot be colored again, the Color tab
is disabled.
• The Presets list box enables to select the color profile using pre-
defined or custom presets.
• The Coloring Control area displays the active quad image
histogram and enables to create a color profile.
Right-licking into the histogram area adds the vertical borderline
with a divided triangle on top (right-clicking onto an existing one
removes it). Pressing and dragging a borderline changes its
position along the histogram. Clicking onto the left / right part of the
triangle selects the left / right border color. The image gray scale
between two borderlines is linearly transformed to a new color
spectrum.
• The Hand button enables to select and color a particular image
gray level. Clicking it opens the color selection dialogue: select a
color and press the OK button. The mouse cursor changes to the
hand image. Click the feature image you want to highlight. New
borderline is added into the histogram with a rectangle on top. The
selected grey level is marked with the chosen color. You can move
this borderline and change its color the same way as a borderline
with a triangle on top. By dragging the rectangle left / right side the
highlighted grey level range could be changed.
• The Enable check box switches on / off actual color settings for
the active quad image.
• The Save button saves the actual setting as the custom preset.
The Process Tab
Here the user can set parameters, which adapt image when clicking
the
Apply button, or when selecting the Tools menu / Image Post
Processing (Ctrl + F7). The Undo button, or the Tools menu / Undo
Image Post Processing (Ctrl + Shift + F7) reverts the corrections
back.
• The Denoising strenght (0 / 1 / 2 / 3 / 4) removes dust and
scratches from the image.
• The Sharpening strenght (0 / 1 / 2 / 3 / 4) corrects the image
sharpness.
The Custom settings could be saved.
Note:
This functionality works only with greyscale images (not colored via
Color tab), images which are paused or with loaded saved ones.
